Stix3D 27 Flies
It’s all done, the smallest RC plane I’ve built. 27 inch wingspan for indoor and backyard flying. Dirt cheap electronics, no extra weight-loss measures (ie- no carbon fiber pushrods, no cellfoam, no contest weight balsa) , 2 cell 800mA battery, 1800kv motor from my Chinese cousins at HK, towerpro 5 gram servos, 1.5mil doculam covering. CG was a bit too far back for my tastes and some shuffling is called for, but it’s a hoot to fly this little bat.
Thanks to Ron at the Probro forum for the plans. The build thread is here: http://www.theprofilebrotherhood.com/forum/viewtopic.php?f=20&t=33132
I deviated from the plans by using a NACA 0015 airfoil. I lasercut a dual-taper rib pattern from 11″ to 7.5″ chord. http://airfoiltools.com/airfoil/details?airfoil=naca0015-il If anyone wants a ribset cut let me know…. it’s already in the computer.
